Thank you for the reply. I'm reporting this as a bug so it can get fixed in the distro, even if I'm able to resolve it on my machine. I looked but I didn't find the bug reporting site. I'm able to do user management with "User Accounts".

How can this be reported as a bug in Netrunner if this is not the right place?

We do not ship or support the upstream Plasma user-manager. This is why the user-manager package is not installed, and it's KCM has been diverted (hidden) by default under Other. We do however ship and support the User Accounts utility from Manjaro Settings Manager. The User Accounts utility is integrated right into the Plasma System Settings, and is the first item you'll find under the System section. This utility is more advanced than the upstream User Manager utility, and even allows for changing account types per user, as well as individually setting the groups associated with each user account for a more customized user account type.
